            Fixed security-related bug in

            working.
          
            Fixed bug that made OPTIMIZE TABLE to
            corrupt the table under some rare circumstances.
          
            Fixed mysqlcheck so it can deal with
            table names containing dashes.

            field with <=> NULL.

            BY queries that didn't return any result.
          
            Fixed a bug where MATCH ... AGAINST ()
            >=0 was treated as if it was
            >.
          
            Fixed core dump in SHOW PROCESSLIST when
            running with an active slave (unlikely timing bug).

            One can create TEMPORARY
            MERGE tables now.
          
            Fixed that --core-file works on Linux (at

Allocate heap rows in smaller blocks to get better memory usage.

            Fixed a bug in key optimising handling where the expression
            WHERE column_name = key_column_name was
            calculated as true for NULL values.
          
            Fixed core dump bug when doing LEFT JOIN ... WHERE
